IMPROVEMENT IN CARRIAGE-TOP PROP-BLOCK WASHERS.

Specification forming part of Letters Patent No. 122,205, dated December 26, 1871.

Specification describing a new and Improved Carriage-Top Prop-Block Washer, invented by ABRAHAM D. WESTBROOK, of Astoria, in the county of Queens and State of New York.

Figure 1 represents a side view of a carriagetop prop-block provided with my improved washers. Fig. 2 is a transverse section of the same.

, Fig. 3 is a face view of the flanged washer; Fig.

4, a central section of the same. Fig. 5 is a face view of the plain washer, and Fig. 6 a central section of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to an improvement on the prop-block for which Letters Patent No. 52,126 were granted to W. N. Barnett, January 23, 1866. The rubber propblock shown in said Letters Patentis provided with flanges at the end.

In manufacturing such articles it has been found that there is a difference in the length of posed, but were not durable, nor as yielding to V to the ends of the rubber prop-blocks and secure- 1y held in place thereof.

A in the drawing represents a rubber propblock of the kind above referred to. B B are the washers, made of India rubber, and applied to the ends of the propbloeks. Each washer has its edge nicely finished to give a pleasant appearance to the entire block, and is 011 its inner face provided with a projecting flange, c, as in Figs. 1 and 4, which flange overlaps and covers the end of the block A, and is in part out out to admit the upper rib Zgof the block. However, it may also be made without such flanges, as in Figs. 5 and 6,though not by preference. A polygonal hole is formed through the washer for the admission of the fastening bolt.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- As an imprqyed article of manufacture, the rubber carriage-top prop-block washer, made substantially as herein shown and described.
